This invention relates totap bushings and has more particular reference to tap. bushings adapted for use in conjunction withbarrels .or kegs which are subjected to considerable gaseous presof the barrel part to hold the bush securely in placieandito clamp together endsi'of': the, ma-

terial. constituting the 'kegpart opening;

While one embodiment of: thisiinve'ntion is illustrated i inv the accompanying rdraiwing; it is to tension piece B so as to rest on the bottom of the threads, or brought to rest on the. tapered portion of the cone shaped cylindrical portion B. When the flange G is seated the extension B extends slightly below the flange and may be rolled over or crimped at H to lock the flange G to the bush and to simultaneously clamp together the opposite circumferential edges of the bush receiving opening of the head J illustratively shown as supported in suitable barrel staves K. The foregoing arrangement provides an arrangement in which the annular flange G is located on the inside of the barrel so that the space between the bush and opening resulting from the insertion of a tapered bush in the bored bush receiving opening is effectively sealed. The ring A which is forced firmly against the opposite side of the barrel part by the crimping or rolling action and. the bush so clamped not only effectively prevents leakage into the space between the tapered end and the bored opening but slightly compresses the ends of the material constituting the barrel or keg head and this is of especial importance in wooden kegs whether solid or laminated to prevent deterioration by seepage of the barrel contents into the ends of the material surrounding the bush.

It is claimed:

Tap bushing for beer barrels combining with a compressible barrel part having a bored opening, of a tubular member having integral therewith at one end thereof a flange for engagement with one side of the barrel part, and having a part at the other end thereof for extension beyond the other side of the barrel part, and a part tapering inwardly to said extension part between the latter and said flange, and a separable auxiliary flange embracing said extension of the tubular member, seated in a depression in the adjacent face of the compressible barrel part,

and in part seated on said tapered portion of the tubular member; the extension portion of the tubular member being rolled over and set to the auxiliary flange under pressure sufficient to form said depression and to effect such seating of the'auxiliary flange, and the auxiliary flange being held in said seating by the rolledover part of the tubular member.
